JOHN GREGSON, OF GARY, INDIANA.

OIL STOVE AN D BURNER.

Specification of Letters Patent.

Patented Nov. 2'7, 1917.

Application filed January 25, 1917. Serial No. 144,499.

To all whom it may concern:

Be it known that 1, JOHN Gnnoson, a citizen of the United States, residing at Gary, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in Oil- Stoves and Burners, of which the following is a specification.

My invention relates to new and useful improvements in oil stoves and burners, the primary ob'ect of my invention being the provision 0 an improved form of crude or other oil burning stove for heating purposes which may be economically manufactured, easily set up and which will be effective in use.

A still further object of my invention consists in providing a stove of this character in which the lower portion of the stove body constitutes the bowl portion of the crude oil burner.

Another object which I have in view is the provision of a heating stove in which the base orsupport of the stove is formed with draft openings communicating with the body of the stove so that air is drawn into the burner from all sides to insure both a uniform burning of the fuel and also effective ventilating of the room in which the stove is used.

With these and other objects in view, my invention will be more fully described, illustrated in the accompanying drawings, and then specifically pointed out in the claims which are attached to and form a part of this application.

In the drawings:

Figure 1 is a central vertical sectional view, partially in elevation, of my combined stove and burner;

Fig. 2 is a transverse sectional view taken on the line 22 of Fig. 1;

Fig. 3 is an unassembled sectional view of the burner includin the bowl which forms the lower portion 0 the stove body;

Fig. 4 is a section taken on the line 4-4 of Fig. 1, showing the burner in plan view; Fig. 5 is a corresponding section, showing the urner with its distributing cap removed;

Fig. 6 is a view corresponding to Fig. 1, illustrating a modified form of burner construction;

Fig. 7 is a fragmentary sectional view, sliowing the modified form of burner in p an.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

My improved stove body includes a base 10, lower body portion 11, intermediate bod portion 12, and top 13. The base 10 is pre erably rectangular in shape and hollow in construction, being formed from metal as a single casting or of sheet metal, as preferred, and being provided with feet 14 for supporting it above the floor. All of the side walls of this base 10 are formed with air inlet openings 15 and its top wall is formed centrally with an outlet opening 16. The lower body portion 11 of the stove is in the form of a c lindrical bowl open at its upper end and having its bottom 17 formed centrally with an opening 18 concentric with but greater in size than the opening 16 in the base and surrounded by an upwardly directed cylindrical burner forming flange 19 which is preferabl at least half the height of the bowl. his lower body portion seats upon the base and may be either permanently or detachably secured thereto. The flange 19, adjacent its upper open end, is provided with a series of air openings 20. The intermediate body member 12 is cylindrical in shape and open at each end, being arranged at 1ts lower end to engage over the upper end of the bowl 11, as shown at 21. This intermediate portion is provided at one side with a swinging door 22 and the top portion is provided with an opening surrounded by a flange 23 to receive a flue pipe 24. The top portion of the body is in the form of a dome shaped at its lower end to engage about the upper end of the body member 12, as shown at 25, and serves merely as a closure or top for the stove.

The burner proper of this stove includes not only the bowl 11 and burner flange 19, but also a circular concavo-convex superheater plate 26 which closes the upper end of the inner cylindrical body portlon of the burner, heretofore called the burner flange 19. This su er-heater plate is disposed with its convex ace uppermost and is provided centrally with an opening which receives a nipple 27 to which may be connected a fuel supply pipe 28 leading upwardly through the base of the stove and through the alined openings 16 and 18. By this means, the crude oil, which constitutes the preferred fuel for this stove, ma be discharged upon the upper surface of t e super-heater plate. This plate is further provided with a lurality of upwardly directed studs 29 w ich serve as a support for a circular concavo convex distributer cap 30 which is disposed with its convex face uppermost and supported in spaced relation above the plate. This cap is considerably larger than the super-heater plate and at its peripheral edge is provided with a laterally directed annular flange 31 which projects nearly to the inner face of the wall of the bowl 11 and which acts to deflect the flame of the burner outwardl against the wall.

If esired, this distributer cap may have its flange proportioned to engage snugly within the bowl of the stove, as shown in Figs, 6 and 7, under which circumstances the flange will be formed with a series of peripherally spaced openings 32 for the passage of the flames. Otherwise, the stove structure shown in Figs. 6 and 7 is identical wth that shown in the remaining figures.

In operation, crude or other oil is admitted through the pipe 28 until some of it has accumulated in the bottom of the bowl and ignited. The heat from this burning oil highly heats the inner cylindrical portion of the burner and the super-heater plate, with the result that further crude oil flowing from the pipe is vaporized and -ignites u on meeting air entering through the openings 20 so that an intense annular flame or zone of combustion is provided immediately below the distributer cap which serves to deflect this flame outwardly against the body of the stove and which also serves to retard its passage toward the flue so as to insure complete combustion of the vapor before it passes fromthe stove.

By admitting air to the base of the stove from all sides a more uniform burning of the fuel is insured and the stove also serves a valuable purpose as a ventilator for the room in which it is used.

Obviously, a combined oil stove and burner constructed in the manner described may be economically manufactured and readily set up. Furthermore, the burner, because of its simplicity, needs but little attention and its parts are readily accessible when such attention is necessary.

It will of course be understood that I reserve the right to make any changes, within the scope of the appended claims, without in the slightest degree departing from the spirit of my invention.

Having thus described the invention, What is claimed as new is:

1. In a combined stove and burner, a base, a stove body supported upon the base and formed at its lower end with an opening surrounded by an upwardly directed cylindrical burner body formed with openings, means for supplying air through the opening in the stove body, a concave-convex superheater member closing the upper end of the burner body with its convex face presented uppermost, fuel supply pipe projecting upwardly through the superheater to discharge fuel thereon, and a concavo convex distributer supported upon the su erheater with its marginal portion depen ing about and below the marginal portion of the superheater.

2. In a combined stove and burner, a base, a stove body supported upon the base and formed at its lower end with an opening surrounded by an upwardly directed cylindrical burner body formed with openings, means for supplying air through the opening in the stove body, a concavo-c0nvex superheater member closing the upper end of the burner body with its convex face presented uppermost, a fuel supply pipe projecting upwardly throughthe superheater to discharge fuel thereon, studs projecting upwardly from the superheater, a concaveconvex distributer removably supported upon the studs with its convex side uppermost and with its marginal portion depending about and below the marginal portion of the superheater, and a peripheral flange formed on the distributer at its lower edge and projecting laterally with its edge slightly spaced from the wall of the stove.

3. In a combined stove and burner, a base having an opening for the passage of air, a hollow annular stove body member closed at its lower end seating upon the base with its central opening alining with the opening of the base, the hollow annular body bein open at its top and its outer peripheral wa being extended above its inner peripheral wall and its inner peripheral wall being formed with air openings, a superheater resting upon the inner peripheral wall and closing the central opening of the annular member, a fuel pipe arranged to discharge fuel upon the superheater, a distributer su ported above and in spaced relation to t e suprheater, and an upper stove body portion detachably engaging the outer wall of the annular body member.

In testimony whereof I aflix my signature.
